A FIBER OPTIC TERMINAL SYSTEM EMPLOYING SUBCARRIER MULTIPLEXING FOR HIGH CAPACITY OPTICAL DATA TRANSPORT

摘要

A system and method employing subcarrier multiplexing is described. In one embodiment, the system comprises tributary interfaces (101), modems (103), frequency converters, a radio frequency (RF) multiplexer (104), and an optical transmitter (105A). The tributary interfaces (101) accept input data channels. The modems (103), which are coupled to the tributary interfaces (101), modulate the input data channels onto an intermediate frequency (IF) carrier. The frequency converters, which are coupled to the modems (103), translate the input IF channels to RF frequencies. The RF multiplexer (104), which is coupled to the frequency converters, combines RF channels. The optical transmitter (105A) is coupled to the RF multiplexer (104) and modulates the combined RF channels onto an optical carrier and then transmit the signal into a fiber.
